To demonstrate the utility of ultrafast noncontrast MRI in the imaging and diagnosis of suspected ectopic pregnancy, in clinical situations where ultrasound is nondiagnostic.

Maimonides Medical Center is a tertiary care facility, with a busy OBGYN service, and the highest number of deliveries of any hospital in NYS. Given this environment, suspected ectopic pregnancies are not uncommon. The department of Radiology and OBGYN have developed a collaborative effort and protocol to utilize noncontrast MRI as an adjunct to diagnose suspected ectopic pregnancy in cases where ultrasound is nondiagnostic (secondary to concomitant pelvic masses, field of view issues, body habitus, bowel gas, and operator dependence). Ultrafast multiplanar MRI sequences-HASTE T2 and TRUE FISP are utilized to make the diagnosis quickly and efficiently without the above described constraints. We report several cases of histologically proven ectopic pregnancies diagnosed with MRI as well as standard protocols utilized.

Ultrafast MR imaging without gadolinium is a safe, quick, and efficient diagnostic examination that provides critical information when the clinical suspicion of ectopic pregnancy is high and ultrasound findings are inconclusive.
